SPRING-WHEEL.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed April 4, 1913. Serial No. 758,838.

To all whom it may concern:

Be it known that I, GEORGE H. SoHANoK, a citizen of the United States,residing at Libertyville, in the county of Lake and State of Illinois,have invented certain new and useful Improvements in Spring-VVheels, ofwhich the following is a specification.

This invention relates to that class of spring wheels in which thespokes are resilient, and its object is to provide a novel arrangementof spring or resilient spokesand means for securing the same, as will behereinafter described and claimed.

In order that the invention may be better understood, reference is hadto the accompanying drawing in which- Figure 1 is an elevation of thewheel. Fig. 2 is a cross section on the line 22 of Fig. 1, and Fig. 3 isa section on the line 8-3 of Fig. 2.

Referring specifically to the drawing 5 denotes the hub of the wheel,and 6 indicates the rim, the latter being equipped with a suitable tire7. Each spoke is a flat strip of suitable metal, semicircular in shape,and tapering in thickness toward the end which is connected to the rim.One end of the spring is rigidly secured to the rim and the other end tothe hub, the points of attachment being diametrically opposite eachother, but not at the opposing edges of the rim and hub. The spring,from its point of attachment to the hub, extends in a semicircularcurve, and is carried to the rim, to which latter it is fastenedopposite that edge of the hub which is diametrically opposite the edgeto which the inner end is attached. This arrangement permits the use ofa relatively long spring, and a maximum resiliency and easy riding isobtained. Bolts 9 are employed for fastening the springs to the rim.

The following fastening for the inner ends of the spokes 8 is provided:The hub has a laterally extending peripheral flange 10, the outersurface of which latter is formed with alternating depressions andraised portions similar to ratchet teeth. The raised portions 11 havetheir outer surfaces convexly curved to conform to the curvature of theinner ends of the springs, the latter being placed so that their concavesides seat on the curved outer surfaces of the parts ll. Each spring isthus seated, and over its endis placed a cap 112 having side flanges 13which lap the sides of the parts 11. Through the caps, and the springbeneath the same, are passed bolts 14 which are secured by nuts 15, thelatter being screwed on the bolts against the inner periphery of theflange 10.

By the fastening herein described themner ends of the spokes aresecurely connected to the hub, and they can be readily connected orremoved.

Between the flange 10 and outer face of the hub 5 extend webs 16 forstrengthening the parts.

I claim:

A spring wheel comprising a hub having a laterally extending peripheralflange, the outer surface of which flange has alternating raisedportions and depressions, a rim, resilient spokes secured at one end tothe rim .and having their other ends seating on the aforesaid raisedportions, caps fitting over the last-mentioned ends of the springs, saidcaps being co-extensive with the raised portions of the hub flange andabut-ting against the shoulders formed thereby, said caps also havingside flanges lapping the sides of the raised portions, and fasteningmeans passing through the caps, the last-mentioned ends of the springsand the flange.

In testimony whereof I aflix my signature in presence of two witnesses.
